Coronation Street looks set for explosive scenes next week as Stephen Reid's downfall is teased as his plan to spike Carla Connor's drink with LSD backfires. Viewers will recall that Stephen has been spiking Carla's drink on the ITV soap recently as "vile" revenge, which recently resulted in Carla woozily driving the Underworld van into Paul Foreman who was on Peter's bike. In upcoming episodes, Stephen gets a taste of his own medicine when he accidentally drinks Carla’s tea, which he spiked with LSD, just before he goes on stage to do a presentation for the new business.
